“From its compact footprint to its commanding presence, the Rival Defender-SB isn’t just a welding skid—it’s proof that power and precision can thrive in any truck bed.”

Defender Short Box

Premium Short-Box Welding Skid with No-Compromise Strength, Storage, and Style.

The Rival Defender-SB Welding Skid is the definitive choice for welders running short-box trucks who refuse to sacrifice capability for size. Built from marine-grade 5052-H32 aluminum and 6061-T6 extrusions, the Defender-SB delivers the same rugged, feature-rich performance as its larger siblings in a compact, perfectly balanced package. With dedicated oxygen, acetylene, and propane storage, integrated LED-lit cabinets, a 3000 lb Rival steel equipment slider, and quick-fist pipestand holders, it transforms any short-bed pickup into a professional-grade mobile welding station. Precision-engineered, Canada-rated, and field-tested, the Defender-SB gives small-bed trucks big-rig capability.

The Unrivaled Short Box Skid

The (not so) secret power of the Defender-SB lies in its balance of compact design and full-size performance. Crafted from 5052-H32 millplate aluminum and reinforced with 6061-T6 extrusions, it’s built on Rival’s proprietary steel sub-frame for maximum rigidity and safe load distribution. Purpose-built for 6′ 6″ domestic ¾-ton and larger pickups, the Defender-SB includes LED-lit storage cabinets with a full-length drawer, rod-tube holders, and dual oxygen and acetylene pillars for secure bottle storage. A 3000 lb steel equipment slider accommodates Lincoln and Miller engine drives, while integrated reel mounts, pipestand holders, and a steel workbench tailgate make the Defender-SB a self-contained welding command center.
Installation is straightforward (completed in a single day at Rival Truck in Parksville, BC) with built-in forklift pockets and removable lifting lugs for safe handling. Standard finishes include bare aluminum or Sandtex black powder coat, with customization options for color, layout, or additional drawer systems. Backed by Rival’s two-year parts and labor warranty, the Defender-SB brings unmatched organization, durability, and professional presentation to any short-box truck. It’s compact. It’s complete. And it’s built to lead.
